A prism is filled with 60 cubes with 1/2 unite side length

What is the volume of the prism in cubic unites?

Answer:

2/3

Step-by-step explanation:

7 red, 5 yellow, and 6 orange  =18

P( red or yellow) = number of red or yellow / total

                           = (5+7)/18

                             =12/18

                             =2/3

Answer:

false

Step-by-step explanation:

4 x (2) = 8

Answer:

False

Step-by-step explanation:

What you need to do is plug 2 in for g.

4g=32

4(2)=32

8=32

This is incorrect, so it is false.

Answer:

37 years

Step-by-step explanation:

If the mean age of 5 people in that room was 25 years,

∴ Sum₍₅₎= (25×5)years

              = 125 years

When a person enters that room, the mean age was now 27.

∴ Sum₍₆₎=(27×6) years

              = 162 years

∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎

                                                                                 = (162-125) years

                                                                                 = 37 years

∴ The age of the person who entered the room is 37 years.

Answer:

The answer you are looking for is 1

Step-by-step explanation:

Any number raised to the power of one equals the number itself. Any number raised to the power of zero, except zero, equals one. This multiplication rule tells us that we can simply add the exponents when multiplying two powers with the same base.

Answer:

15/16

Step-by-step explanation:

The probability of not getting all heads is

1 - P(all heads)

P (all heads) =P(heads) *  P(heads)* P(heads) * P(heads)

                      1/2* 1/2 * 1/2 * 1/2 = 1/16

1 - 1//16 = 15/16

Answer:

Step-by-step explanation:

(i) Area of ABCD = (base1+base2)*height/2

                           = (6+12)*4/2 = 36 cm2

(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3

(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25

                    = 72                         + 250      + 150   + 300

                    = 772cm2

Answer:

164 people

Step-by-step explanation:

100% represents the 150 people who attended last year.

this year , there is an increase of 9% , which will make the total percentage to be 109%.

if ; 100% = 150 people

     109% = ?

cross multiply to get 163.5 the round off to get 164

x=10

Step-by-step explanation:

    2x+6 = 6x-34

-> 10 =x

Answer: 32

Step-by-step explanation:

There are 18 boys and 14 girls (4 more boys than girls.  32 students total.

If the ratio of boys to girls is 9 : 7, there are 32 students in this Year 9 group altogether.

Let's denote the number of boys as "9x" and the number of girls as "7x" since the ratio of boys to girls is 9:7. We are also given that there are 4 more boys than girls, so we can set up an equation:

Number of boys = Number of girls + 4

9x = 7x + 4

Now, we can solve for "x":

9x - 7x = 4

2x = 4

x = 2

Now that we have the value of "x," we can find the number of boys and girls:

Number of boys = 9x = 9 * 2 = 18

Number of girls = 7x = 7 * 2 = 14

Finally, to find the total number of students in the group, we add the number of boys and girls:

Total number of students = 18 (boys) + 14 (girls) = 32.

The ratio of boys to girls is 9:7, and there are 4 more boys than girls.

Answer:

x=14

Step-by-step explanation:

4x-y=21

y=3x-7

Substitute the second equation in for y in the first

4x - (3x-7) = 21

Distribute the minus sign

4x -3x +7 = 21

x +7 = 21

Subtract 7 from each side

x+7-7=21-7

x=14

Answer:   x=14 is right answer

4x-y=21 =

Slope = 4

x-intercept = 21/4 = 5.25000

 y-intercept = 21/-1 = -21.00000

y=3x-7 =

Answer:

That's the answer attached, whatever answer matches up with it is correct.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

To calculate the area of this triangle we can use the Heron’s formula

Mathematically we have the Heron’s formula as;

A = √s(s-a)(s-b)(s-c)

where s = (a + b + c)/2

Thus, s = (15 + 12+ 10)/2 = 18.5

a = 15, b = 12 and c = 10

Plugging these values into the equation, we have

√18.5(18.5-15)(18.5-12)(18.5-10)

= √18.5(3.5)(6.5)(8.5)

= √ 3,577.4375

A = 59.8116

which is approximately 59.8 square units

Answer:

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

She sold:

1/3 on Tuesday.

5/12 on Wednesday.

What fraction of blue shirts did she sell on Tuesday and Wednesday?

Sum of fractions.

The lesser common multiplier between 3 and 12, which is 12.

So

[tex]\frac{1}{3} + \frac{5}{12} = \frac{\frac{12*1}{3} + \frac{12*5}{12}}{12} = \frac{4 + 5}{12} = \frac{9}{12} = \frac{3}{4}[/tex]

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Answer:

we are going to use BODMAS

7.(2+18) -14

is also 7×(2+18) -14

since B representing bracket comes first,

we add the numbers in the bracket.

2+18=20

7×(20) -14

then M representing multiplication comes next do we multiply.

7×20=140

140-14=126

that's it!

Answer:

P(red) = .3

P(yellow) = .3

75 cubes in the box

Step-by-step explanation:

The probability has to add to 1

Since the number of red cubes equals the number of yellow cubes the probability has to be the same

.4 + x+x = 1

.4 +2x = 1

2x = 1-.4

2x = .6

Divide by 2

x = .6/2

x = .3

P(red) = .3

P(yellow) = .3

We know that

P(blue) = .4 = number of blue cubes/ total number of cubes

                 .4 = 30/total

                  total = 30/.4

                   total = 75

Answer:

The ball is 7 feet above the ground 2 seconds after it is thrown.

Step-by-step explanation:

As per the given statement, we are given a graph of function [tex]f(x)[/tex] where 'x' is time (in seconds) in the current scenario.

Time is plotted on x axis and height of football is plotted on y axis.

[tex]f(x)[/tex] is the height of football according to change in time.

Following are the few things that can be observed from the given curve:

1. Initial Height of football is ~4.8 feet i.e. at 0 seconds of time.

2. Football reaches a maximum height of ~7.2 feet at 1.5 seconds.

3. After 1.5 seconds, the height of football starts decreasing.

Here f(2) means, the height of ball at 2 seconds of time.

It is clearly visible from the given graph that height is 7 feet at 2 seconds.

Please refer to the attached answer image. Height at 2 seconds is marked as point P.

Hence, The ball is 7 feet above the ground 2 seconds after it is thrown.
